What the ASRS v1.1 measures
Six adult ADHD symptom cues over the previous 6 months.
The six-question ASRS v1.1 screener samples problems with finishing details, organization, remembering obligations, starting effortful tasks, fidgeting, and feeling overly driven or active. It is designed to identify people who may benefit from a fuller adult ADHD evaluation.

14+ is a positive-screen threshold—not a diagnosis
The official 2024 scoring update describes a 0–24 total with a positive-screen cutpoint of 14. A positive screen means further evaluation may be useful.
Scoring and interpretation
How this free ASRS result is calculated
Each answer is scored 0 for “Never,” 1 for “Rarely,” 2 for “Sometimes,” 3 for “Often,” and 4 for “Very often.” The six item scores are added for a total from 0 to 24.
This implementation follows the official ASRS v1.1 scoring update posted in 2024. That update notes that the 0–24 dimensional score was more robust than the older 0–6 shaded-box rule for research and prevalence work, with 14+ used as the positive-screen cutpoint.
The complete score and screening interpretation are free.
What a clinician adds
An ADHD evaluation looks for history and impairment.
A qualified clinician may ask whether symptoms were present earlier in life, whether they occur in more than one setting, and whether they cause meaningful problems at work, school, home, relationships, finances, driving, or daily organization.
They also consider sleep, anxiety, depression, trauma, substance use, medical conditions, medication effects, and other explanations that can resemble ADHD.
What this screen can and cannot tell you
A positive screen means “look closer,” not “you have ADHD.”
The ASRS is useful because it is brief and standardized. But ADHD diagnosis requires a broader clinical evaluation, including developmental history, impairment, context, and exclusion of alternative causes. A negative screen also does not automatically rule ADHD out if significant problems are present.
Clinical review and use limits
This screening implementation should not be treated as a validated clinical or diagnostic tool unless an independent qualified reviewer verifies the exact ASRS version, wording, current scoring rule, rights notice, age positioning, privacy flow, and U.S.-first care guidance.

Frequently asked questions
Before you take an adult ADHD screen
Does a positive ASRS screen mean I have ADHD?
No. It means your answers reached a screening range where a fuller adult ADHD evaluation may be worth considering.
Why does the test ask about the last 6 months?
The ASRS asks about recent adult symptom frequency over a six-month period. Diagnosis still requires broader developmental and functional history.
Can anxiety, depression, or poor sleep look like ADHD?
Yes. Several conditions and circumstances can cause attention, organization, restlessness, or memory difficulties. That is one reason professional assessment matters.
How to use the result
An adult ADHD screen answers a narrower question than an ADHD diagnosis
The ASRS v1.1 can flag whether current adult ADHD symptoms deserve a closer look. It cannot establish childhood onset, determine whether symptoms occur across settings, or rule out sleep problems, anxiety, depression, substance use, medical conditions or other explanations for concentration difficulty.
| If your result is… | A useful next question |
|---|---|
| Low or negative | Are attention problems still causing meaningful impairment despite the screening result? |
| Elevated or positive | Have these patterns been longstanding, present in more than one setting and traceable to earlier development? |
| Mixed | Could sleep, mood, anxiety, stress, medications or another condition be contributing? |
Use the score as a prompt to describe concrete examples. A clinician can combine those examples with developmental history, functioning and differential assessment. Read adult ADHD symptoms and assessment or ADHD vs anxiety for context before interpreting the screen too broadly.
